ANSWER
The points (1,2) and (7,2) lie on the given curve.
EXPLANATION
The given parametric equations are:
and
We make t the subject in the first equation to obtain:
We substitute this into the second equation to get:
When x=1,
When x=2
When x=7,
Therefore the points (1,2) and (7,2) lie on the given curve.
The image is a dilation of the pre-image with a scale factor of 3.
